Bacillus megaterium. Last updated: 28/05/2018. (Not known by any other names) GENERAL INFORMATION. Description. A Gram-positive, aerobic eubacterium used as a soil inoculant. Example pests controlled. - The soil-related Bacillus and Paenibacillus species have increasingly been implicated in various human diseases. Nevertheless, their identification still poses problems in the clinical microbiology laboratory and, with the exception of Bacillus anthracis and Bacillus cereus, little is known on their pathogenicity for humans. In this study, we evaluated the use of matrix-assisted laser. Bacillus spp. are ubiquitous spore-forming bacteria that typically occur as saprophytes in soil and water, but some species, B. cereus in particular, can cause food poisoning. This chapter covers the general characteristics of pathogenic Bacillus species, the nature of Bacillus food poisoning and their growth and survival characteristics. Risk factors associated with Bacillus food poisoning.

Summary: Out of nine strains of Bacillus megaterium from culture collections, only five grew in a minimal medium that contained glucose and ammonium sulphate as principal nutrients. One strain required biotin, while three other strains required two or more amino acids for growth. A freshly isolated strain of B. megaterium required three amino acids for growth Based on the results of biochemical tests, 16S ribosomal DNA analysis and pathogenicity, the causal agent was identified as B. megaterium. This bacterium was reported to cause bacterial leaf spot on Radermachera sinica in China. This is thought to be the first report of bacterial leaf spot on P. frutescens caused by B. megaterium in China
